. APPARATUS FOR DISTRIBUTING CONCRETE.

To @ZZ whom may concern.' i l n ide-it known that L' Burns MGC. ,BEAN- iunLn, a citizen of the United `Si tates,residing. in the cityand countyof San Franc1scoy and State oic California, have inventedv certain tus' for DistributingConcrete, of which the following-is a succiflic tion.- A Y: *I i y 'My invention that class of concrete distributing au, s inwhich a distributing system o troug conveyors are used in co elevator tower.

The object of niyinvention is .potion with an to provide 15 an apparatus of this class, simple, practical and eii'ective in construction, and which will permit indefinite range of distribution,

To this end .my invention consists in the novel apparatus which shall now fully dedrawings, in which- Figure l is a side elevation of my con- `prete distributing apparatus. 2 is a fragmentary horizontal` section on the'line velevation of Ione or' the conveying troughs.

. Secured to the boX on each `side around the spouts lO'is a short-chute` 13, each of said chutes having, as vshowny 2, two divergent branches le,y under. the outer end voi? each of which isA a., short head-trough l5, Supported from-the tower by links-151', as seen in Fig. 1. @ne of? these headtroughs leads -in. `the direction. of and underlies one of the guy-cables 7, andthel other leads similarly to an adjacent guy-cable, thus providing, as shown clearly ,in Fig. 2, four such head-troughs, one for each guy-cable.

Within the bozi 9, as shown in Figflyand in .dotted lines in' 1,'s. removably ttted a directing platey9". In the position shown this plate delivers the concrete to the spout l0 on the right; but when the plate is changed to the opposite angle, itdeliverstheeoncrete -to the spout onthe left. Ineach` short chute 13-where its branches Alt lead oii, is placed a vcontrolling plate y16,1as seen in F ig. 'I This plate may slide into place or it may be hinged, thelatter being indicated. lts position is such that it can close either-branch 14C` and open the other. 4, 17, in Fig.1, isA the'rnain trough.` VThis composed of a plurality of freelyl overlapping sections in end' alinenient, as shown in Figs. 3 and 4. Thesections are flexibly connected or `articulated in ysuitable manner. A good construct-ion'is thatshown in said Figs. 3 and 4, namely rods-.18 seated in the curled edges 190i the trough sections, the meeting ends of said rods being 'hooked to! gether as shown at 20. The main trough 1*" 1s suspended from and carried by any one of the guy-cables 7 by suitable hangers, such, for example, asv the bails 21. The uppetfend. ot the main trough A17 lies under any pneof the head-tronghs l5 in position to receive the'concrete therefrom.l

Suspended ,from the Aguy-cable y7 from Cfl which the main-trough 17 is suspended is a end 4of said main-trough is adjustably carried and held in position to discharge the concrete into the hopper I24. .The other ends of the spider-arms'are secured to a shield 30, the lower `'end of which iits freely -into the hopper, and its upper end/is carried by an adjustable collar 31 on the hanger-rod 22.

The hopper 24 is fitted Witha discharge spout 32. Under this spout'lies the upperv end of the second trough 33, as shown in Fig. 1. This trough is similar in construction to the main-trough, that is'composed of articulated sections. It is 'suspended b bails -34 from a cable 35l the upper end o which is secured to the guy-cable 7, and the lower end of which is connected to a xed point by a block and'tackle at 36, as seen in Fig. 1. This second trough may be the terminal of the distributing apparatus or more troughs '20 may be added. For example, I show in Figs.

1, 7 and 8 provision for a third trough 37.'

This trough has'an enlarged head 38 and is suspended by bails 39 from a'beam 40. The

. upper end of this beam has a bracket 41 which is revolubly carried on a hanger 42 suspended from the cable 35. A bail 43 flexibly connects the lower end of the second trough 33 with the hanger 42, said end being disposed properly to deliver the concrete into .30 the enlarged head 38 of the third trough 37.

The lower end of the beam 40 is supported on a foot block 44 to which it is secured by a .handled bracket 45.

The operation of the apparatus is as fol- -lowsz-The concrete 1s carried up by the elevator 4 and dumped into the box 9. By the late 9 in said box, the concrete 'is directed into the spout 10 to the right. Byv the platev 16 in the cl1ute13 of this spout, it is directed 4o into that head trough 15 with which the main trough 17 is in communication. The concrete passes down through the main trough 17 and is delivered into the hopper 24 which ldelivers it to the4 second trough 33.

45 Assuming the second trou h to be the termipositions nal of the system, itvwill e seen that by re leasing the lower end of the cable 35from which it hangs and carrying said cable around and securin -it in successively fresh in itscirc e of movement, the second trough 33 turns with its revoluble hoper 24 through a completecircle' and will deliver the concrete throughout its range of movement. The area thus served can be env`larged by removing some. of the. terminal sectionsof sections ofthe second trough 33, slipping-the connections of thecable 35 and the hopper hanger rod 22 farther up on the guy-cablelv?,

'I 60 and lengthening the cable 35 by its block and tackle 36. When the area within range of the apparatus as thus described has been served, the main l the guy-cable 7 which had previously supported it, and said trough is moved bodily to the main trough 17, adding to the,

trough 17 is unslung from-A a new relation with another head trough 15 of the box 9` and isthen suspended from an Vother of the guy-cables 7. In vthis readjustment to a new position, the second trough 33 accompanies it, the cable 35 of said trough easly manipulation through its handle 45.

n this general type of apparatus for distributing. concrete'I am aware that it is not new to providefor a circular range of distributive area and to augment this range by a series of secondary areas, said result being .conveying systems. ever, to support the tower, bybooms and overslung cables. But there is a practical limit to such suport, both in the strength ofthe tower and 1n the'leverage, weight and length of the pipes. yIn contradistinction to this customary method, the essential feature of my invention lies in the'suspension of my distributingsystem from a catenary support.' This gives many advantages, such, for example,

system to reach any given distributivearea,

gest-themselves to workers in this art, and of which I may state but one more but `very decided benefit, namely, that arising from the remixing or further mixing of thel material owing to the flow or passage of said material inthe catenary curve'of the trough lso suspended, permitting a vminimum amount of mixing in the preliminary mixer machlne.

u ThoughI have hereink shown'the catenary support for the maintrouh as the guy-cable of the tower, I do not con ne myself to this.

Suchvsupport may be any suitable catenary,
